The present invention relates to methods and arrangements for resolving radio resource conflicts occurring in radio networks supporting both local ad-hoc communication and cellular communication. The conflicts are resolved by informing the cellular network about radio resource management restriction
The present invention relates to methods and arrangements for resolving radio resource conflicts occurring in radio networks supporting both local ad-hoc communication and cellular communication. The conflicts are resolved by informing the cellular network about radio resource management restrictions due to the local ad-hoc communication needs and resources that are reserved for local ad-hoc communications.
